Tool drummer Danny Carey is scheduled to sit in with Primus on three September touring dates. The band's original drummer, Tim "Herb" Alexander, is currently recouping from open heart surgery following a heart attack last month.

"The mighty Tim 'Herb' Alexander is a polyrhythmic Viking of extreme and unique talent so the one person that we thought could step into his shoes and do it justice is the one and only Mr. Danny Carey," Primus frontman Les Claypool told Rolling Stone.

"I can't wait to see that menacing grin of Danny's shine out as we pound our way through 'Here Come the Bastards' and 'Those Damned Blue-Collar Tweekers'. He's a dear old friend and we are extremely excited to have him aboard."

Primus will play at the Riot Fest in Chicago and Denver, as well as an after party at Chicago's Concord Music Hall on September 13.
